- Pressure restricting valves are used when flowing water pressure needs to be controlled.
- NFPA requires restricting valves where the inlet pressure exceeds 100 PSI. Unlike the pressure regulating type of valve, the restricting valve has no effect on the static pressure of a system.
- Restricts only under flow conditions
- Restricts inlet pressure from 70 PSI up to a maximum of 175 PSI and down to outlet pressures of 65, 80 or 100 PSI.
- Outlet pressures may be set below 65 PSI when authorized by the local authority having jurisdiction. Setting charts are packed with the valve.

How it works
- Restricting valves are angle valves with preset orifices which restrict the volume of water and thereby lower the pressure of the flowing water.
- The restricting device can be manually bypassed if required by opening the valve fully. Simply pull the pin to allow the yoke to fall back from the valve stem to allow the valve to be opened fully. When the valve needs to be restricted again, slide the yoke back into place to be NFPA compliant.
